The developers at Mozilla have migrated the main repository of the Firefox source code from Mercurial to Git. The official Git repository for Firefox is hosted on GitHub. Currently, changes cannot be submitted via pull requests through this repository (Phabricator must be used instead). <\/p>\n
Some individual Mercurial repositories have been combined into a single Git space and are accessible via Git branches: the mozilla-central repository is now the main branch in the Firefox Git repository, mozilla-beta is the beta branch, mozilla-release is the release branch, mozilla-esr115 is the esr-115 branch, mozilla-esr-128 is the esr-128 branch, and autoland is the autoland branch. The use of Bugzilla, moz-phab, Phabricator, and Lando will continue unchanged. The old Mercurial repositories remain accessible for now but are switched to synchronized mirror mode. <\/p>\n

Prior to the migration, the project provided the option of using either Mercurial or Git at the developers' discretion, but Mercurial was mainly used in the primary repositories. Supporting both systems placed a heavy load on the administrators, and maintaining the code independently led to scaling issues and consumed resources necessary for sustaining a fault-tolerant infrastructure. Therefore, it was decided to limit development to Git only and host the primary repository on GitHub. hosting<\/a> Additionally, a corrective release of Firefox 138.0.3 has addressed several issues: <\/p>\n
